Common Errors in Fluorescence Spectroscopy
In this post we discuss the phenomena of second order diffraction through a monochromator and the problems it can cause in fluorescence spectroscopy.
In this application note, emission properties of a phosphorescent organic light emitting diode (PhOLED) are investigated using an FS5 Spectrofluorometer equipped with the electroluminescence accessory. The spectrum and chromaticity coordinates of the PhOLED emission are measured and the triplet lifetime determined using time-resolved spectroscopy.
In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum. The most ubiquitous type of spectrometer used for research are optical spectrometers; and when someone simply says ‘spectrometer’, without an additional qualifier, they are usually referring to an optical spectrome...
Edinburgh Instruments, has designed multiple spheres for each of its photoluminescence spectrometers, the FLS1000 and FS5, that allow the most sensitive measurements over the widest dynamic and wavelength range using single photon counting based detectors and electronics.
